Set list maker app send MSB LSB Program for changing preset in drumjamirig blueboard send strat/stop in drumjam drumjam is on backgroud audio that's allPerhaps this settings are not called interapp ,i'm not sure...

After a moment the drumjam preset changes but it doesn't respond anymore to strat/stop.

So, you can tell the preset changes because it is already playing in the background? Or do you have to open the app? Even with the drumjam in the foreground the start/stop MIDI commands don't work after a certain time?

With the drumjam in the foreground the start/stop MIDI commands work perfectly.

In background:After a certain time,Drumjam doesn't start ,i open it and i have seen the preset have changed.And then i can start it with my pedal ( blueboard)(if i open and close it (drumjam) ,strat/stop start working again)

During my set ,Drumjam doesn't playing audio all the time ,only a few songs.
